Elasticsearch deprecations
Review the deprecated functionality for your Elasticsearch version. While deprecations have no immediate impact, we strongly encourage you update your implementation after you upgrade.
To learn how to upgrade, check out <uprade docs>.
To give you insight into what deprecated features you’re using, Elasticsearch:
- Returns a
WarnHTTP header whenever you submit a request that uses deprecated functionality. - Logs deprecation warnings when deprecated functionality is used.
- Provides a deprecation info API that scans a cluster’s configuration and mappings for deprecated functionality.
